* Note: a separate listing for Hispanic is not included because the US Census Bureau considers Hispanic to mean persons of Spanish/Hispanic/Latino origin including those of Mexican, Cuban, Puerto Rican, Dominican Republic, Spanish, and Central or South American origin living in the US who may be of any race or ethnic group (white, black, Asian, etc.); about 15.1% of the total US population is Hispanic.

Immigration has contributed to many of the economic, social, and political processes that are foundational to the United States as a nation since the first newcomers arrived over 400 years ago. After brushes with immigration reform that began in 2001 and continued in 2006 and 2007, the United States seems to be on the threshold of overhauling the legal immigration system in the most substantive way since 1965. This article provides a comprehensive overview of major legislation and events affecting U.S. immigration throughout history, legal and illegal immigration flows, postrecession immigration trends, and more.

Recent Activity

While many countries are increasing engagement with their diasporas, U.S. policy has chiefly focused on U.S.-based diasporas from other countries, despite its own estimated overseas population of 7.6 million. This feature explores results from a survey of more than 1,400 U.S. citizens and 140 former citizens living abroad, many of whom are critical of limited U.S. government engagement with them even as restrictive financial reporting regulations have been imposed.

With more than 1.8 million immigrants living in the United States, the Philippines was the fourth largest country of origin in 2013. Filipino immigrants stand out from other top immigrant groups with their unique historical experience as former nationals due to U.S. annexation of the Philippines in 1899, close historic ties to the U.S. military, and prevalence in health-care professions.

In 2013, more than 25 million people in the United States reported limited English proficiency (LEP), an 80 percent increase since 1990. The LEP population, the majority of which is immigrant, is generally less educated and more likely to live in poverty than the English-proficient population. This Spotlight explores key indicators of the LEP population, both U.S. and foreign born, including geographic distribution, language diversity, and employment.

As legal challenges continue to impede President Obama's deferred action programs to protect millions of unauthorized immigrants from deportation, it is becoming increasingly clear that the window of opportunity for implementation before the 2016 election is growing ever narrower. Even as advocates continue mobilizing immigrants to apply, attention is shifting to other new policies announced by the president last November.

Immigration to the United States from the Middle East and North Africa (MENA) region has increased in recent years, rising to a total population of 1.02 million in 2013. Immigrants from the region come from a diverse range of countries and cultures. This data Spotlight delves into the variations among MENA groups on key socioeconomic indicators, from geographic distribution and language proficiency to employment, immigration pathways, and naturalization.

Mexico has lost its long-held status as the top source country of new immigrants to the United States, dropping to third place behind China and India. This historic shift is remarkable for the rapid decline in Mexican inflows combined with a steady rise in Asian immigration, largely through high-skilled visa programs. This Policy Beat explores the reasons behind these trends and their potential impact on U.S. demographics.

Indian immigrants represent the second-largest origin group in the United States, accounting for 4.7 percent of the total foreign-born population. Generally high-skilled and highly educated, more than half of Indian immigrants have arrived since 2000 and largely attain green cards through employment-based pathways. Indians account for 70 percent of H-1B petitions and are the second-largest group of international students in the United States.

The H-2B visa allows U.S. employers to bring in foreign workers to temporarily fill low-skill nonagricultural jobs across a wide range of states and industries. A series of recent legal challenges has exposed the presence of fraud and abuse, while stripping the program of its regulations and raising uncertainty about its future. This Policy Beat examines the implications in the debate surrounding temporary worker programs.

Cuban immigrants are afforded a special place in U.S. immigration law, with most able to gain permanent residency after one year in the country. Following a history of surges in maritime migration, more than 1.1 million Cuban immigrants resided in the United States in 2013, accounting for about 3 percent of the total foreign-born population. This article explores key characteristics of Cubans in the United States, including educational attainment, income, and more.

Immigrant women constitute a varied and dynamic population in the United States with 51 percent or 21.2 million of the country's total foreign-born population. Examining key gender-based socioeconomic indicators from origin and fertility to educational attainment and immigration status, this Spotlight raises implications for sending and receiving countries, with respect to labor opportunities, family structure, gender roles, and more.

The guide also includes additional links to relevant organizations, programs, research, and deliverables, along with a glossary of frequently used immigration terms.

Voters’ brains connect words, phrases, images, values, and emotions, and these connections — known as networks of association — influence their receptiveness to political messages, often far more strongly than facts and rational arguments. This report shows that to reach those who have not yet made up their mind on a particular issue, advocates and leaders need to understand the associations a term such as “immigrant” spark in the mind of the electorate and strengthen positive associations while weakening negative ones.

Immigration is a prominent part of the United States’ DNA, despite concerns about immigrants’ ability to integrate. An examination of recent immigrant inflows shows newcomers to the United States are integrating well, based on language proficiency, socioeconomic attainment, political participation, residential locale, and social interaction indicators.

This report examines the role of naturalization as indicator and facilitator of successful integration in the United States. It examines why immigrants decide to naturalize and why many of those eligible to naturalize are unable or choose not to do so.

Low-income immigrant children are less likely than their U.S.-born citizen counterparts to see a doctor even when they are insured. Similarly, immigrant adults are less likely to use emergency rooms than low-income natives. This report examines health care coverage and usage among immigrants and the U.S. born.

Since its launch in 2012, the Deferred Action for Childhood Arrivals (DACA) program has intertwined immigration policy and the education and training fields in an unprecedented way. Based on fieldwork in seven states, this report examines the ways in which local educational institutions, legal service providers, and immigrant youth advocates have responded to the first phase of DACA, as well as the program's effects on students' educational and career aspirations.

This report evaluates the United States Visitor and immigrant Status Indicator Technology (US-VISIT) program within the broader contexts of national and homeland security as well as immigration law enforcement and policymaking. In doing so, the author provides constructive criticism along with a framework for rethinking US-VISIT’s goal priorities, investment needs, and deadline expectations.

This exploratory study provides an unprecedented assessment of the “brain-waste” phenomenon in the United States—a serious waste of human capital resulting from the unemployment or underemployment of highly skilled college-educated immigrants.

This report examines existing collaborative teacher exchange programs some U.S. states and districts have established with Mexico and Spain, and identifies such programs as a relatively unexplored, yet promising strategy for alleviating endemic teacher shortages and meeting the needs of LEP students.

This report examines the trilateral relationship between the United States, Canada, and Mexico in the decade since the North American Free Trade Agreement (NAFTA) and provides facts and figures relating to trade and migration among the three countries.

This fact sheet compares key components of immigration reform outlined in the 2013 Senate immigration bill against provisions included in bills considered by the Senate in 2006 and 2007: border security, detention, and enforcement; worksite enforcement; visa reforms; earned legalization of unauthorized immigrants; strengthening the U.S. economy and workforce; and integration of new Americans.

This report closely examines the rapid growth of government appropriations directly targeted to immigration enforcement activities since the passage of the Immigration Control and Reform Act of 1986 (IRCA). Focusing primarily on data between 1985 and 2002, authors highlight trends in the overall immigration enforcement spending as well as in specific activities.

This report examines the sweeping changes in the way identity documents are issued and used under the REAL ID Act, an effort to enhance the security of identity documents in post-9/11 America. It takes a detailed look at how this legislation will affect document issuing agencies, state budgets, and the employment verification system, in addition to immigrants and citizens.

Repealing birthright citizenship for U.S.-born children of unauthorized immigrants, a step discussed in some circles as a means to reduce illegal immigration, would significantly increase the size of the unauthorized immigrant population in the United States, from 11 million today to 16 million by 2050, this brief reveals.

This briefprovides a historical overview of various attempts at implementing workplace enforcement in the United States before arguing in favor of a process not unlike credit-card verification that allows employers to swipe a card at the point of hire and receive a response in real time from the Social Security Administration informing them whether an employee is authorized to work in the United States.

This brief argues that an essential first step to any type of U.S. legalization must be a registration process that rapidly identifies, screens, and processes potential applicants. The government could successfully administer a large-scale legalization only with a well-crafted bill, sufficient funding, an unprecedented mobilization of public and private stakeholders, and intensive planning.

Thisreport provides an overview of United States border enforcement throughout the 20th century, highlights how it has changed since the passage of the Immigration Reform and Control Act nearly two decades ago, and further examines its unprecedented expansion in the aftermath of 9/11. The author concludes with a set of policy questions.

This policy brief shows that more unauthorized immigrants in the United States have been legalized through population-specific and registry programs than through the 1986 Immigration Reform and Control Act general legalization provisions.

This policy brief examines the flaws in the United States’ existing employer sanctions regime and proposes six types of reform that could strengthen the system: improvements to document security, document consolidation, mandatory use of employment databases, increased enforcement staffing, a revised penalty structure, and better worksite access for investigators.

This policy brief examines the legalization debate on both sides of the Atlantic and discusses policy parameters that characterize legalization programs, such as qualifications, requirements, benefits, and program design and implementation.

This report examines the connections between the United States’ temporary and permanent systems of admission to the United States. It describes the goals and structure of each system, discusses the relationship between immigrant and nonimmigrant admission flows, and describes the critical data gaps that impede understanding of the underlying realities of immigration to the United States.

This brief demystifies the technical meaning of going to the “back of the line”—a phrase adopted by lawmakers to convey the intent to grant legal status to unauthorized immigrants only after existing backlogs have been cleared—by explaining what “the line” refers to, who is in it, and what it means to be at the back of it.

This volume, which brings together research by leading economists and labor market specialists, examines the role immigrants play in the U.S. workforce, how they fare in good and bad economic times, and the effects they have on native-born workers and the labor sectors in which they are engaged. The book traces the powerful economic forces at play in today’s globalized world and includes policy prescriptions for making the American immigration system more responsive to labor market needs.

Securing the Future seeks to define what policymakers and scholars mean by integration while attempting to sketch the contours of U.S. integration policy. The volume reviews evidence of immigrants’ integration by examining the progress of the second generation, as well as trends in education, health, the workforce, and citizenship.

This interdisciplinary volume examines the health, well-being, school readiness, and academic achievement of children in Black immigrant families (most with parents from Africa and the Caribbean)—a population that has had little academic attention even as it represents an increasing share of the U.S. Black child population.

This edited volume develops a pragmatic approach to the engagement of highly skilled members of the diaspora for the benefit of their countries of origin. The book, edited by a World Bank senior economist, is based on empirical work in middle-income and high-income economies.

Over the past four years, the United States has resettled far fewer refugees than it did in the 1990s. The decline has stemmed partly from post-9/11 security measures. But this book explains other, deeper reasons, deriving from changes in how and why refugees move, how asylum states receive them, and the world community's response. It also suggests steps to restore the program and better address real refugee needs.

The book focuses on three case studies: the United States, the United Kingdom and Germany. The volume includes chapters analyzing public opinion and media coverage of immigration issues in each country. Additional chapters propose strategies for unblocking opposition to thoughtful, effective immigration-related reforms.

This volume, by a former senior counsel to the 9/11 Commission, argues that the U.S. approach to immigration and border security is off-kilter and not keeping pace with the scope and complexity of people’s movement around the world, nor with expectations regarding freedom of movement.

This edited volume rigorously assesses the 1996 U.S. welfare reform law, questions whether its immigrant provisions were ever really necessary, and examines its impact on legal immigrants’ ability to integrate into American society.
